运行M-x-git-gutter：打开或切换到缓冲区并保存缓冲区时清除

Question

我使用Emacs Live，其中包含git-gutter.el。问题是它与linum-mode的效果不佳。运行 M-x git-gutter:clear时，问题已解决。我希望在我的init.el函数中包含一个函数，只要我切换到现有缓冲区或打开一个新缓冲区，它就会执行git-gutter:clear。我还希望在保存缓冲区时运行（通过 C-x C-s ）。感谢。

(defun user2475612-forward-window ()
  (interactive)
    (other-window 1)
    (git-gutter:clear) )

(defun user2475612-backward-window ()
  (interactive)
    (other-window -1)
    (git-gutter:clear) )

(add-hook 'window-configuration-change-hook (lambda ()
  (git-gutter:clear) ))

(add-hook 'change-major-mode-hook (lambda ()
  (git-gutter:clear) ))

(add-hook 'after-save-hook (lambda ()
  (git-gutter:clear) ))
